I saved the best peony card for last: here is the suit's animal. Every hanafuda site I have found simply identifies it as 'butterfly.' Since I made fancy peonies, I figured I'd might as well pick a fancy butterfly to go along with them, so I used a swallowtail for reference. Fly, little swallowtail, fly! Be wary of the ominous red clouds above you.

That wraps up the peonies. Fun fact: we have made it halfway through the full hanafuda deck. With half the suits completed, I still have to draw six more months/flowers/suits, which is 24 cards. I hope you'll keep checking back as I work my way towards completing the deck.
